Mysterious AC issue
 

On my 2005 non turbo minI the ac was blowing ice cold . Shut it off then one day only hot air.

checked all the fuses and relays. To it to my local shop. The checked the system did a evacuation and refill no leaks. They recheckEd the fuses and relays , the pressure switch. Then advised me to take it the dealer.

Dealer does all the same checks, concludes that it is the climate control module, advises to install new climate control.

ordered/installed , nothing changed, return back to my local repair shop.
the lead test the climate control unit , it functions properly. They can turn on the AC unit with a direct line to the compressor it blows cold.


they concluded the signal from the climate control switch is not reaching the Ac clutch.
But they do not have a fix


again 2 repair faculties have checked all relays fuses and pressure switch. All functioning properly
I’ve spent $500 to get a dead end and sit in the heat

could this be a programming issue . Is it in transport mode .

any ideas are welcome
